Transfer songs from iPod to iPod?

the music files are hidden in a folder in the iPod... you need to enable "Show hidden files and folders" in folder options, if xp look in the top of the folder for folder options if 7 or vista look in control panel... than you can see hidden folders in the ipod which contain your music, the problem is that it has a weird name, such as g2sdl23okiads or something like that, you need to copy it to your computer, add to iTunes and i tunes will straighten things up, and than puttin it in the ipod should be easy :D
